Modelling and Simulation in Materials Science and Engineering, 25(3). http://dx.doi.org/10.1088/1361-651X/aa5ce3Enhanced gradient crystal-plasticity study of size effects in a beta-titanium alloy(IOP Publishing Ltd, 2017) Demiral, Murat; Nowag, Kai; Roy, Anish; Ghisleni, Rudy; Michler, Johann; Silberschmidt, Vadim V.A calibrated model of enhanced strain-gradient crystal plasticity is proposed, which is shown to characterize adequate deformation behaviour of bcc single crystals of a beta-Ti alloy (Ti-15-3-3-3). In this model, in addition to strain gradients evolving in the course of deformation, incipient strain gradients, related to a component's surface-to-volume ratio, is accounted for. Predictive capabilities of the model in characterizing a size effect in an initial yield and a work-hardening rate in small-scale components is demonstrated. The characteristic length-scale, i.e. the component's dimensions below which the size effect is observed, was found to depend on densities of polar and statistical dislocations and interaction between them.Article Citation Count: Liu, Qian...et al.
